And it doesn't even tell you the substance. If you say "super glue", I have no idea what to do. If you say "cyanoacrylate", I can get it for a euro.

Yes, some chemical details about how each substance works would make this site fabulous.

To be fair, the page for "Super Glue" does mention it: https://thistothat.com/glue/super_glue.shtml https://thistothat.com/glue/super_glue.shtml ("This is cyanoacrylate.") which then links to: https://thistothat.com/glue/cyan.shtml https://thistothat.com/glue/cyan.shtml which in turns links to the relevant brands' pages. It could be expanded, since not all brands on the site have this, though.

  Yeah, I mentioned that because it was the only chemical I knew, but the general point still stands.
  - toby- 7y ago
    Oh, my bad -- definitely a fair point and I agree. I would love to see an internationalised version of this website with chemical details, and perhaps more safety information.

    Can you can give an example that supports your point, instead of making a general point and one example that disproves it?
    - StavrosK 7y ago
      What do you mean? Most of the examples I've seen didn't mention the chemical name: https://thistothat.com/cgi-bin/glue.cgi?lang=en&this=Ceramic&that=Fabric https://thistothat.com/cgi-bin/glue.cgi?lang=en&this=Ceramic... https://thistothat.com/cgi-bin/glue.cgi?lang=en&this=Ceramic&that=Glass https://thistothat.com/cgi-bin/glue.cgi?lang=en&this=Ceramic... https://thistothat.com/cgi-bin/glue.cgi?lang=en&this=Ceramic&that=Leather https://thistothat.com/cgi-bin/glue.cgi?lang=en&this=Ceramic... etc.

I had a hard time finding CA glue here in the Netherlands until I discovered it is what we just call secondenlijm ('secondsglue'). Also whenever I find a tube or bottle of superglue I am always tempted to attach a red cape to it (using glue of course).

  Similarly, we call it "instant glue". I had no idea it was the same until I looked at the ingredients.

I love cyanoacrylate adhesives. With paper/cardboard you get a composite that's almost fiberglass. With nylon (anything from stockings to ripstop) you get even closer. Or silk or kevlar. All of them react exothermically with cyanoacrylate, so they cure very quickly.

  I use it mainly for plastics, where it works very well (I managed to break the plastic before the CA bond). However, yesterday I had one fail when I used it in the sink (and thus was wet a lot). I have no idea why water ruined the bond, but I used an epoxy for it and hope it will be okay now.

    Cyanoacrylate works well with plastics that it dissolves. So it's like solvent weld plus glue. Polystyrene, polycarbonate and PVC, for example. Or materials with hydroxyl groups, with which it reacts. Such as paper, wood, silk, rayon, nylon and kevlar. But not polyethylene. And not polystyrene foam, because it melts it. My favorite for that is Gorilla Glue. I don't know what's in it. But it has something that reacts with water (which is the catalyst) and also the same materials that cyanoacrylate works well with. But it doesn't melt the foam, just melds with it. What bond failed in the sink, if I may ask?
    - StavrosK 7y ago
      For polystyrene foam, I use UHU Por (not sure what the chemical is), it makes it brand new. I have an EPP wing that I crashed three times and broke into pieces, and Por makes it brand new again. The bond that failed was PLA to PLA (I 3D-printed a soap holder, so the surface wasn't very smooth either). I don't know if it was the water or if I didn't apply enough glue or what.

        I'm not familiar with PLA. Maybe this: https://hackaday.com/2018/02/07/locally-sourced-pla-adhesive/ https://hackaday.com/2018/02/07/locally-sourced-pla-adhesive...
